Objective The aim of this study is to examine the effect of myoophenolate mofetil (MMF) on epithelial-myofibroblast transiation(EMT) in adenine-induced chronic renal failure (CRF) rat model and the role of vascular endothelial growth factor(VEGF) and inhibitor of differentiation (Id2 and Id3) in EMT in the rat kidney. Methods Sixty-four male Wistar rats were randomly assigned to the following groups: normal control (n=16), CRF (n=24) and MMF(n=24). CRF was induced by gastric gavage of adenine (125 mg·kg-1·d-1) to rats for eight weeks. CRF rats were treated with MMF (15 mg·kg-1·d-1) as "MMF" group. The rats were sacrificed at week 2, 4, 6 and 8, respectively.Urinary protein and serum ereatinine levels were measured, and the histopathologic degrees of interstitial fibrosis were evaluated in Massen-stained sections. Expressions of a-smooth muscle actin (α-SMA),transforming growth factor β1 (TGFβ1), VEGF and Id (Id2 and Id3) in the kidney tissue were assessed by immunohistochemistry, RT-PCR and/or Western blot methods. Results The urinary protein level in MMF group was evidently lower than that in CRF group (P<0.01), whereas no statistically significant difference was observed in serum creatinine level between the two groups. Renal interstitial fibrosis was reduced significantly with MMF treatment (P<0.01). Expression of α-SMA in MMF group was lower than that in CRF rats at week 6, 8 (P<0.01), while expression of TGFβ1 was decreased markedly at week 2, 4,6 (P<0.01). The expressions of VEGF in MMF rats were increased significantly at week 6,8 (P<0.01),and Id2,Id3 in MMF rats were increased significantly at week 4,6 (P<0.05). Conclusions MMF may ameliorate chronic renal fibrosis and EMT in adenine-induced CRF rats. This effect of MMF on EMT is probably related to upregulation of VEGF, Id2 and Id3 expressions and suppressing overexpression of TGFβ1 in renal tissue. The exact mechanism needs to be studied further.

Objective To discuss the therapy for acute gastric mucosal lesion(AGML)after pericardial devascularization of advanced schistosomiasis. Methods Fifteen advanced schistosomiasis patients with AGML after pericardial devascularization re-ceived supporting therapy,reducing stomach acid and protecting gastric mucosa therapy,reducing gastric blood flow therapy,en-doscopic spraying topical hemostatic agents or electric coagulation therapy,etc. Results After pericardial devascularization of ad-vanced schistosomiasis,15 patients occurred AGML,and among which,10 cases occurred from 8 to 14 days,and the shortest pe-riod was 5 days and the longest was 23 days. Among the 15 patients,13 patients were cured(86.7%),and 2 died. Conclusion The comprehensive therapy including supporting therapy,reducing gastric acid and protecting gastric mucosa,and endoscopic he-mostasis is effective in the treatment of AGML.

Objective To examine the relationship of the inhibitory effect of vascular endothelial growth factor(VEGF) on epithelial-mesenchymal transition (EMT) induced by TGF-β1 in HK2 cells with the expression of connective tissue growth factor (CTGF) and PI3K-Akt pathway. Methods The cultured HK2 cells were divided into the following groups: normal control group, TGF-β1 (5 μg/L) group, VEGF (100 μg/L) group, TGF-β1 plus VEGF group. LY294002 (25 μmol/L), the blocker of PI3K-Akt pathway, was added to each of above-mentioned groups for the second part of the study, α-smooth muscle actin (α-SMA) and E-cadherin expressions of HK2 cells were assessed with double-stain immunocytochemistry method. The mRNA and protein expressions of α-SMA and CTGF of cells were assessed with RT-PCR and Western blot. The expressions of fibronectin (FN) and collagen Ⅰ (Col Ⅰ) in medium were assessed with ELISA. Results The expressions of α-SMA and CTGF significantly increased in HK2 cells treated with TGF-β1 compared with those in normal control (P<0.05), while significantly decreased in cells co-treated with TGF-β1 and VEGF compared with those treated with TGF-β1 alone (P<0.05, respectively). The expression of E-cadherin was exactly opposite to that of α-SMA. When LY294002 was added to TGF-β1 and VEGF co-treated cells, the expressions of α-SMA, CTGF, FN and Col Ⅰ were markedly up-regulated, when compared with those without LY294002 treatment (P<0.05). Conclusion Inhibitory effect of VEGF on TGF-β1-induced EMT of HK2 ceils in vitro may be related to down-regulation of CTGF expression and reduction of FN and Col Ⅰ, which may be partly dependent on PI3K-Akt pathway.

Objective To observe the curative effect of electro-acupuncture combined with rehabilitation training to shorten the period of flaccid paralysis after cerebral infarction.Methods 78 victims were divided into treatment group and control group at random. The treatment group received electro-acupuncture combined with rehabilitation training, and the control group received rehabilitation training only. Muscular tension was evaluated on the 15th day and 30th day after admission according to the modified Ashworth spasm rating scale.Results The number of flaccid paralysis victims in the treatment group is significantly less than that in the control group (P＜0.05) on the 15th day and 30th day after treatment.Conclusion Electro-acupuncture combined with rehabilitation training can shorten the period of flaccid paralysis after cerebral infarction significantly.

Objective To study the accuracy of an ultrasonographic characteristic diagnostic score system(UCDSS) which was used to classify the breast solid nodular lesions. Methods UCDSS were established by analyzing the ultrasonographic sign of the 205 breast solid nodular lesions. These lesions were classified according to the total scores of each ultrasonographie sign. ROC curve was used to evaluate the value of UCDSS. Results The area under ROC curve of UCDSS was 0. 977, the sensitivity and specificity was 92.0%, 92.3% respectively. Conclusions The classification based on the UCDSS may increase the diagnostic accuracy of the differentiation between benign and malignant breast solid nodular lesions.

OBJECTIVE: To investigate the incidence rate of the ampC gene and AmpC enzyme of gram-negative(G-) bacterium in children,to analyze drug resistance of produced AmpC enzyme and un-produced AmpC enzyme strain.METHO_DS: 4 022 clinical G-isolates collected from 2002 to 2004 were identified and tested using K-B method.Selection 108 ESBLs bacterium,the ampC genes were amplified by PCR using common primers to AmpC and the AmpC enzymes were tested using the enzymatic rough extraction cefoxitin three-dimensional test.The drug resistance of bacterium produced AmpC enzymes were compared with the ones without AmpC enzymes.RESULTS: In 108 G-bacterium,the ampC genes positive bacterium were 70 strain(accounting for 64.8%),and 7 bacterium produced AmpC enzymes(accounting for 6.5%) were detected.The drug resistance of bacterium produced AmpC enzymes to ceftazidime(CAZ),ceftriaxone(CRO),piperacillin(PIP),ampicillin(AMP),aztreonam(ATM) were 85.7%,85.7%,71.4%,79.4%,79.4% respectively.The drug resistance of bacterium non-produced AmpC enzymes to CRO,PIP,gentamicin,AMP,ATM were 50.8%,55.6%,55.6%,70.3%,54.0% respectively,the drug resistance of bacterium to imipenem were the lowest,lower to ciprofloxacin.CONCLUSIONS: Detection rate of ampC gene were higher than AmpC-producing enzymes strains obviously,whereas the drug resistance to antibiotic of AmpC-producing enzymes strains were higher than non-producing enzymes strains.

Objective To correct the high supratarsal fold after cosmetic upper blepharoplasty is a challenge because of the shortage of both upper eyelid skin and fat.Levator shortening has been a procedure of choice selected by the surgeons to correct this condition.Methods Under local anesthesia, the desired crease was marked according to the characteristics of eyelid anatomy and aesthetic consideration for Asian women.The incision was made through the marked new skin crease and the old incision with surrounding scar tissue was incised.The adhesion between the skin and the levator aponeurosis was completely released.The levator aponeurosis was then divided above the tarsal plate.It could be shortened and then reattached to the tarsal plate depending on the amount of the upper eyelid skin and the degree of the ptosis.The skin incision was then closed to form new but lowered fold.Results Between 2003 to 2015, a total of 34 Chinese women underwent bilateral levator shortening for correction of high supratarsal fold after previous unsatisfactory upper blepharoplasty by other surgeons.There were no surgical complications postoperatively in this series and 32 patients (94.1%) were satisfactory for the outcome of the proper height of the supratarsal fold with at least 1 month follow-up.Only one patient (2.9%) required surgical revision for asymmetry of supratarsal folds and one patient (2.9%) for correction of deepened supratarsal fold.Conclusions The levator shortening can be an effective procedure to correct high supratarsal fold after unsatisfactory upper blepharoplasty in Asian women.It is especially useful to correct such a condition where there is shortage of the eyelid skin combined with the eyelid ptosis.

Objective To clone and identify the cDNA sequence and genomic DNA sequence of Anopheles sinensis defensin gene. Methods Referring to the published defensin gene sequences of Aedes aegypti and Anopheles gambiae, pairs of primers were designed to amplify the cDNA sequence and genomic DNA sequence of Anopheles sinensis defensin gene with template of Anopheles sinensis total RNA by RT-PCR and genomic DNA by nested PCR, respectively. These amplified fractions were cloned and sequenced, and were further identified and analyzed by relevant bioinformatics softwares. Results Complete genomic DNA sequence was cloned, including 5′ and 3′ UTR fraction and two exons separated by a 85 bp intron. Besides, the whole cDNA sequence of Anopheles sinensis defensin gene with 324 bp was also cloned, and its ORF encoded 107 amino acids. The mature peptide had 40 amino acids residues. Conclusion The whole cDNA sequence and complete genomic DNA sequence of the defensin gene of Anopheles sinensis have been cloned and identified for the first time.

2h.The shape of bacterium was changed by amikacin from sphero-rhabditiform to dolicho-rhabditiform,while by ceftriaxone changed from rhabditiform to long-chain-form or filament-form.Conclusion The capability of ceftriaxone-induced release of endotoxin from Escherichia coli is significantly stronger than that of amikacin,and the morphologic changes of bacteria caused by ceftriaxone were more significant.For clinical treatmentg of infectious diseases the first dosage of medication should increase to reach the effective bactericidal concentration but not the bacteriostasis concentration in order to receive better therapeutic effects.
